摘要: 以(Mo/Mo2O)為參比電極,用固體電解質定氧測頭對熔融鈷基合金中氧活度進行快速測定的效果良好,利用與CoO平衡時氧在鈷液中的溶解度得到了氧在鈷液中的標準溶解吉氏自由能與溫度的關系,為氧活度計算提供了數據.Abstract: Using the solid electrolyte oxygen sensor with (Mo/MoO2) reference electrode to quickly measure the activity of oxygen in molten Co-based alloys, the good results were obtained. The relation was obtained between the standard Gibbs free energy of solution of oxygen in liquid Co which is necessary for calculating the activity of oxygen and temperature by using the solubility of oxygen in the liquid Co being equipoised with CoO.
